The Mandeville Police Department has issued a boil water advisory for residents in the 2300 block of Upton beginning at 9 a.m. Tuesday while the city repairs a water main. The scheduled repair will interrupt water service for about three hours, according to the Police Department.

Residents affected by the repair should boil their water before drinking, making ice, brushing their teeth or using it for food preparation - including rinsing food, according to the notice.

Residents should boil water for one full minute in a clean container. The one minute starts after the water has come to a rolling boil.

The advisory will be lifted once the Louisiana Department of Health and Hospitals tells Mandeville Public Works that the water is safe.
